Research ArticleOpen accessIn the abstractEvaluation of Tensile Strength of the Superficial Digital Flexor Tendon in Horses Subjected to Transcutaneous Electrical Neural Stimulation Therapeutic RegimenDavood Sharifi, Davood Kazemi, Hadi LatifiWe would like to sincerely express our gratitude to the university of Tehran and faculty of veterinary medicine research council for approval and financial support for this extensive evaluation of tensile strength of the superficial digital flexor tendon in horses subjected to Transcutaneous Electrical Neural Stimulation (TENS) therapeutic regimen Problems statement: The purpose of this study was to determine the … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal Time Implementation of NARMA-L2 Control of a Single Link ManipulatorS.S. Mokri, H. Husain, W. Martono, A. ShafieNonlinearities and parametric uncertainties are unavoidable problems faced in controlling robot manipulator. A single link manipulator driven by a permanent magnet brushed dc motor is a nonlinear dynamics due to effects of gravitational force, mass of the payload, posture of the manipulator and viscous friction coefficient. Furthermore, uncertainties arise because of changes of the rotor resistance with temperature and random … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Sliding Mode Speed Control of an Induction MotorKais Jamoussi, Mohamed Ouali, Hassen CharradiField-oriented control was combined to robust sliding mode for motor speed control. A smooth continuous function was added in order to overcome chattering caused by Sliding Mode Controller (SMC). Simulation results showed that improvement made by our approach compared to classical PID control. …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractDamping of Generator Oscillations Using an Adaptive UPFC-based ControllerD. Nazarpour, S. H. Hosseini, G. B. GharehpetianIn this study a UPFC-based non-linear adaptive controller is proposed and designed to damp generator oscillations. The adaptive controller design is based on determination of control signal using a new linear quadratic pole placement control law and identification of power system parameters with recursive least squares method with adaptive directional forgetting factor. A new model of UPFC has been introduced … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,764 accessesView PDFCite

Research ArticleOpen accessIn the abstractIdentification of Volatile Metabolites from Fungal Endophytes with Biocontrol Potential towards Fusarium oxysporum F. sp. cubense Race 4A.S.Y. Ting, S.W. Mah, C.S. TeeProblem statement: Fungal endophytes are widely studied for their potential as biocontrol agents towards fungal pathogens. In vitro assessments usually reveal their antibiosis and mycoparasitism nature, but little is understood regarding their production of volatile metabolites as mechanisms of antagonism. Approach: This study explored the potential of fungal endophytes in controlling the pathogen responsible for Fusarium wilt disease. Nine fungal … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 11,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDFCite
